Miyoko stands on the top of a glacier and looks down at the frozen wasteland. She shivers because of the cold and turns around, revealing a large house - made of ice. She shakes her head and starts walking.

The screen turns black. White letters appear and write the words "I won't go back." (戻らない。). For a moment, Akarin is shown standing in the same place as Miyoko did before, but unlike Miyoko, she heads off away from the frozen palace. The next frame is Miyoko singing the first strophe without music playing in the background.

The the camera shows the winter landscape. Miyoko walks over a large mountain. Her footsteps can be seen far behind her until suddenly, Five girls run to her, panting because of running quickly - Mocchi, Iku, Aimi, Rairin and Monica. All of them seem unhappy in the cold.

"What are you doing here?" Monica asks.
"… I wanted to see them." Miyoko replies after waiting for a moment.
"Who?" Aimi asks confused.
"We don't exactly get many visitors here." Iku notes.
Mocchi nods. "No one visits this place. It's at the end of the world."
Miyoko sighs. "…So you really don't remember?"
All girls are confused and about to speak up.

The screen freezes, before the video seems to rewind. It now seems to be morning, and the girls sit in their ice house, drinking hot tea. One of the door opens and Akarin, Sasshi and Takamina walk in. "New people arrived!" She announces; and the 154th Generation and Hikarin follow them. The girls introduce themselves while Miyoko is completely confused. Everyone else seems to consider the situation as completely normal.

"What.…is happening? Senpai?" Miyoko asks. "What are you doing here? Why are they-" Once again, the screen freezes. The video now seems to fast forward. The girls are outside the building, having a snowball fight.

"Aimi! To me!" Monica calls, waiting for to join her. She then attacks Iku and Mocchi on the other side who both aren't happy about the cold surprise. Miyoko once again is surprised. She hides behind a tree to avoid a snowball.

Miyoko has given up. "Eh, guys?" She steps into the middle of the garden. "What are you doing? Where is everyone else?"
"Everyone else?" Aimi asks. "What do you mean?"
"Takamina-san, Sayaka-san, Honoka-chan, Miyagi-san, Acchan, Sasshi, Paruru-san, Akarin and Yuihan - where are they, and why are you using their names?"
"Here…?" Tomomo slowly replies. "Are you alright, Miyo? We are here, perfectly fine."
"No… No!" Miyoko quickly shakes her head. "You're Tomomo! Tomone Kaoru, the best in the universe and so on. You constantly declare that you are better than anyone else."
"What?" Yuuna asks. "Takamina wouldn't do that."
"And her name is, well, Takamina. Takahashi Minami. Not Tomone Kaoru. She's a girl." Haruki adds. "Are you okay, Miyo? Did you not sleep well?"
"or fall onto your head?" Marian adds.
"Where's Akarin? Who of you is Akarin?" Miyoko then asks.
"Akarin?" Hikarin asks. "I don't know any Akarin… Are you sure that you're okay?"
"Yes…" Miyoko mumbles. "I… just got to take a second off. I'll be back." With those words, she runs off. The screen freezes again and rewinds until becoming dark.

The song's instrumental starts to play while Miyoko speaks. Once again, the scenery is shown.
"As long as we can remember, we have been here. Not once, anything had changed. All time seemed frozen and nothing changed. Never someone left, and never anyone came. Until the day, when Akarin introduced those eight new girls to us. I was incredibly happy - something changed." In black and white, the moment of the girls introducing themselves repeats itself. "We had incredibly much fun, and eventually, Akarin asked the eight how they came here. With a ship, they said. So I went out to look for it. This place, and we too, had never changed but when those girls came, I wanted a change. Akarin had gone before me. She had run off to see the ship, and I followed her. And then… I don't know what happened."

The scene cuts once the intro is finished and the first lines are to be sung. The members stand in the middle of the frozen castle. Everything is made of ice and the light is reflected while the first lines are song. Once the second verse starts, Miyoko finds herself back on the hill, now alone.

"Miyo… Just come home. I am sure that we can help you somehow." Haruki says.
"No… There is something wrong… Something is missing!" Miyoko calls out. "I just don't know what anymore…"

The next strophe is sung while the girls, worried about Miyoko, are shown. None of them dares to approach her though. The third and fourth verse is performed in the dance version.

In the following strophe, Miyoko tries to run away in desperation but each time finds herself back in the house with time being turned back. In a corner of the room, she starts crying. The camera moves to Hikarin who seems to be there to cheer her up, but Miyoko doesn't listen. In the ice wall, a silhouette - the real Sasshi - is shown. Hikarin notices the ghost and cries out in fear. Miyoko looks up to what made Hikarin freak out. Sasshi waves, and now is accompanied by Takamina, Yuihan, Acchan, Honoka, Paruru, Miyagi and Sayaka. Sasshi seems to be saying something, but Miyoko can't hear it. She reaches out for them, but only touches the ice.

From this point on, the reflections of the other, missing members - all expect Akarin. The other girls are visibly scared by them, but Miyoko uses them to explain who really is who. The girls don't believe her though. Eventually, Miyoko is once again alone in a room after the others left in disbelief. She stands in front of an empty wall when Akarin's reflection appears. Akarin's hand seems to touch the ice, and Miyoko touches the ice at the same point.
The music stops. "Warmth?!" Miyoko whispers. Akarin smiles in sad happiness before fading away.

Miyoko runs outside, shouting the first phrase of the refrain. "I want to live!" before the music sets in. All members stand in front of the building, now wearing their uniforms, and perform the song. There are several duo shots - Akarin and Miyo, Miyagi and Honoka, Takamina and Sayaka, Acchan and Sasshi, Yui and Paruru. The snow blows up when the refrain ends. Miyoko starts running while singing her solo phrase in the end of the refrain.

She, once again, doesn’t get far. Her own memories of the missing girls start to fade as well, and she desperately holds on her own small memories. She breaks down into the deep snow while a blizzard starts blowing around her. At the house, the other girls are worried about her since she is still outside. The blizzard becomes stronger and stronger, and eventually she is caught in it, unable to move in the snow. Miyoko still cries, but seems to be about to pass out when the blizzard suddenly stops around her. It stills roars, but a small space seems to be unaffected. The music stops to play after the seconds strophe after the first refrain.

"Live."

Akarin stands in front of her. Miyoko slowly looks up.
"Akarin…?"
"It's me."
"You're alive!"
"We all are. And we found a way out of this prison of time."
"But...how?" Miyoko asks, but Akarin simply points to the frozen palace.

The music continues to play and now, the other missing girls travel to the palace in the blizzard. They manage to convince the other girls that the blizzard is endangering the palace too and that they aren't safe. They eventually come while Akarin and Miyoko watch the whole scene from the distance. They eventually join on their way to their ship. The girls step over a certain point of distance from the palace during the phrase "Is this a fantasy?" and suddenly start to remember.

Together, the girls perform in front of the ship. The blizzard stopped and it's snowing a little bit. Hikarin and Harrupi, Monica and Mocchi, Aimi and Rairin, Zelda and Ikuchan, Marian and Elise, Yuuna and Tomomo, Haruki and Miko have duo shots.

The sun comes out from behind the clouds and while the younger girls are confused, the previously missing girls genuly enjoy themselves. During her solo phrase, Akarin is shown laughing happily.

The girls look back at the frozen castle that now starts to collapse in itself while the next verses follow. Miyoko looks up to the sky and to the bright sun, and Akarin next to her smiles. All girls stand together, watching the palace collapsing, and Takamina claims that they are finally free from the frozen prison. Akarin corrects her; they are free of the whole past. They turns around and move towards the ship. Each member shortly gets a solo shot before they start running upon the phrase "I want to live". With Miyo at the front, the girls run in the vague formation of the song towards the ship. The song eventually ends, and the girls finally reach the ship. They board it and fly away, towards the sun. The song's title, "Melting", and "AKB0048" is shown over the image of the blue sky, the sun and the now small space ship.

Out of unknown reasons, Akarin is missing in the MV from the point on, where she watches the castle collapsing with Miyoko. In the first scene, she is still present, but after correcting Takamina, she is gone.

It's a popular rumour that the only reason why Sasshi was the first member to be shown in the ice is because it was easiest to edit her into the video.
